Question

Can someone tell me if I did this right?

The function is defined by f(x)=2x+2
Find f(x+3)

f(x+3)=2(x+3)+2

Final answer : f(x+3)= 2x+6+2

Answer 1

Remember, you can add 6+2. So the final answer would be f(x+3)= 2x+8

Answer 2

That's what I thought but it told me I was wrong.

Answer 3

I just tried 8+2x and it told me I was right.. strange but thanks.

Answer 4

hmm, that's weird. I am 100% sure that my answer is right.

Answer 5

Oh, great, you got it right!
